After an abnormally warm Easter weekend, Monday is predicted to bring a decrease in temperatures and rain to several parts of the UK.

On Sunday, temperatures were predicted to reach the high teens, with the chance of even higher in the south, following Good Friday, which was the hottest day of the year so far with 23.4C recorded in London's St James's Park.

After enjoying the warmest day of the year so far, the UK is poised for mild weather ahead of Easter Sunday.

According to the Met Office, the temperature at St James's Park in downtown London reached 23.4°C on Good Friday afternoon, making it hotter than in California.

Saturday will be somewhat colder, although temperatures in parts of southern and central England are anticipated to reach 22 degrees.

Despite a murky start to the day in certain locations, many portions of the country will have bright, sunny moments.

"It will be a rather overcast start to the morning before evolving into a rather fine and bright day on the whole," Met Office meteorologist Simon Partridge told the PA news agency via the National World.

The West Midlands, in central and southern England, is most likely to see temperatures in the low twenties.

Temperatures will drop on Monday

On Sunday, the weather will progressively drop, with showers in Scotland and Northern Ireland, but most other places should stay nice.

More broadly, some areas will have temperatures in the low twenties, while portions of Scotland and Northern Ireland will experience temperatures in the mid-to-high teens.

On Sunday, cloudier skies were forecasted in the west, with rain outbreaks in Northern Ireland and western Scotland gradually moving eastwards in a week that the UK Met Office said would bring a return to more typical weather for April when the average temperature is around 12C.

It was forecast that temperatures will begin to decrease on Easter Monday, with some rain and cloud rolling in over the week.

Rain would come in from the west tonight, but it would be "weakening" as it proceeded, so the east may stay dry, according to Marco Petagna, a senior meteorologist at the Met Office.

"The assumption is that over the following several days, temperatures will gradually crawl down across the UK," he added, as per The Guardian.

The further south and east you travel, the better your chances of remaining dry, but it will be a little cooler on Monday, with temperatures in the low to mid-teens in some areas in the south-east and low to mid-teens everywhere.

Pollen levels, which are still high across the country, causing harm to those suffering from seasonal allergies, will begin to decline in many areas starting Monday, according to Petagna, who added that Easter Monday may be the last day of the week's dry, bright weather, which saw moderate UV levels also with the sun as strong as it was in August.

The sunny weather over the weekend, along with the fact that it was the first Easter without lockdown restrictions in two years, drew a large number of people to the seaside, with Bournemouth seeing some of the busiest crowds of the year and coastal car parks in Cornwall were full.

The RAC has recommended those returning from weekend getaways travel before 10.30 a.m. or after 6.30 p.m. on Easter Monday to avoid congestion.
